All That Matters

The study of materials is one of the major areas of science, with legions of researchers in physics, chemistry and materials science working on this topic. Condensed matter physics is one of the largest research areas in physics. Yet, it makes me often uneasy how the benefits of materials science are promoted. It is all too often about applications, and not about fundamental physics. How materials such as graphene might revolutionize electronics. And how new physical concepts could be used to develop materials for energy applications: solar cells, batteries and so on. In classical materials science it’s often about tougher materials, such as enhanced steels, and less about the fundamental insights they are based on. Of course, applications are an important aspect in the study of materials. But does this mean that too often fundamental insights are neglected in favour of a material’s commercial potential?

Last week I had the pleasure to attend the World Economic Forum in Dalian, China. The meeting in Dalian is called the Annual Meeting of the New Champions, and in comparison to the more widely known one in Davos it apparently has more a focus on new technologies. How else would it be possible to present the latest advances in lighting technologies as part of a session organized by Nature…

The meeting was actually quite diverse; there were sessions even on topics such as art and Buddhism.  Yet, clearly there was a focus on business and global governance, and in the context of the more technology-oriented approach of this meeting this meant that there were some interesting discussions on sustainable growth, alternative energies, and so on.

But what did I really learn from these? Well, if you keep up with the daily news and analysis anyway, there wasn’t too much new to be learned. Of course, it was interesting to see some of the high flyers in action and to hear their personal assessment on various issues. But this clearly wasn’t the place to formulate grant visions in much detail. One-hour panel discussions are hardly the place for that. It was far more interesting to talk to some of the participants during coffee breaks, and to exchange opinions privately. I also attended a closed session by the WEF’s Risk Response Network. Discussing not only issues such as the risks to the public arising from new technologies but also the problems we have in dealing with risks offered some new perspectives. Perhaps the secret really is to try to get invited for more of those closed sessions.

But unfortunately, the mingling of the more scientific participants and those from business or politics didn’t seem to work too well. The more scientific discussions were hardly attended by business people and vice versa. I think both sides are to blame a little, and there were not even that many science policy types attending that could bridge this gap, with one of the notable exceptions being the Chinese science minister. That seems like a big missed opportunity to me. In this age, new technologies can revolutionize any business rapidly, and being informed about the trends in science can only be good for business.

More generally, it seemed that all those CEOs, representatives of NGOs etc. very much saw the world from their top-down perspective. Some of the discussions seemed quite ‘meta’ to me. In terms of global risks and sustainability for example, there seemed to be the conviction that there are a lot of answers and solutions, but that there is a general failure of political leadership to execute these, with the danger being that the longer we wait the greater the implications if catastrophes unfold. As someone said in one of the discussions, “the motivation of politicians is to get re-elected, not to execute.” This theme was pervasive in discussions on several topics. There was also praise for the Chinese to have their more long-term vision in the form of five-year plans.

Well, this made me a bit uncomfortable. This is very much a top-down approach in the way that these top executives run their company: implement a strategy and everyone has to follow suit. Is this really the public governance we want? Follow and shut up. There was almost no mention throughout on the fact that politics also works to a large degree from the bottom up.

For example, the risk of a global flu pandemic that kills millions within weeks unfortunately is all too real (c.f. swine flu, bird flu). Or earth quakes, tsunamis. If there is indeed a lack of leadership in addressing such threats, then I think this is the result of wrong priorities. Criticising leaders for inactions will only get us that far. If there is a public consensus that certain risks need to be mitigated, leaders can be forced to act from the bottom up. via the public. But to create risk awareness, everyone needs to be aware of such risks in the first place, and this issue is where I think the discussion needs to go.

Anyway, would I attend the World Economic Forum again if given the opportunity? Certainly! The WEF, and those attending these meetings, need more confrontation with science, and more of the bottom-up perspective.

Looking at sheer numbers, science writing is in a boom, enabled by the relative ease of publishing on the internet. Just looking at condensed matter physics and related areas such as nanotechnology, there are wonderful blogs such as 2020 Science, Condensed Concepts, nanoscale views, Soft Machines, and Uncertain Principles. If you do not follow them already, I suggest you take a look.

But despite all the exciting developments in the field, condensed matter physics is not as much in the limelight as say, the LHC or personal genomics. And this despite revolutionary techniques that have a profound impact on our daily life: the transistor, semiconductor lasers, computer hard drives, or the latest advances in nanotechnology, to name but a few.

A few weeks ago, Chad Orzel wrote about this problem in his blog, mentioning that comparatively few people write about the exciting discoveries in condensed matter physics. Doug Natelson took this further and identified a number of problems related to the perceived relevance and profundity of the field, as well as the issue of accessibility for a field whose scientific concepts are often difficult to relay to non-experts.

In my opinion these are of course all valid points, but not impossible to overcome. Of course, it can be a difficult topic to write about. But we need to get the message out more often, so that it sticks better. The problem is certainly not a lack of people in the field. Condensed matter physics researchers make up the majority of members of the American Physical Society. The large body of research they create certainly provides plenty of material to write about.

I have been pondering about the launch of a blog for a while, but constraints on my time have always put me off the idea. However, this recent discussion has finally convinced me that a blog in this area might be of benefit.

In comparison to writers such as Doug and Chad, who are respected university professors, I can offer a slightly different perspective, namely that of an editor of a scientific magazine with experience in research areas ranging from condensed matter physics to chemistry, nanotechnology, materials science and photonics. I frequently discuss current trends and opinions with researchers in these fields. By launching this blog, I hope to bring you some of the exciting stories in this field and hope to increase the interest in a research area that is so relevant to the technologies that we use in our daily life.
